If you do not know PERL at all. Start here. You bet you're gonna learn how to start programming in PERL. At times this may might assume you know atleast some programming language, but generally it is very basic.

This is a great Photoshop CS book. As the other reviewer states, its not for the first time Photoshop user, but if you can handle the basics and you want to learn more, this is the book to get. I've had Photoshop for about a year, playing with it and trying to figure things out for myself, but after reading just 15 pages of this book, I learnt so many more tips and tricks - even for the basic tools! The full colour is really nice to read, and the author guides you through Photoshop in a friendly and helpful, and thankfully not arogant way.

I really recommend this book for the Photoshop user keen to learn more.

The book is probably the best out there (the author works for Microsoft SQL Development) for understanding the underlying SQL architecture (index, transaction logs, locks, data placement on disks etc). This is not a book for the beginners but for those who seek more than superficial understanding of SQL. Nor is this book for those who seek comprehensive knowledge of SQL because it addresses mostly SQL architecture. Nevertheless, I highly recommend this book both for the DBA and the Developers alike.My main qualm with this book is it seems to be hastily written. It reads almost like a late night term paper. This is not to say the information is inaccurate, but the writing of this book is second rate and the author's lack of enthusiasm for explaining the finer points is evident.
